Abstract
The achievable throughput of the entire cellular area is investigated, when employing fractional frequency reuse techniques in conjunction with realistically modeled imperfect optical-fiber-aided distributed antenna systems (DASs) operating in a multicell multiuser scenario. Given fixed total transmit power, substantial improvement of the cell-edge area's throughput can be achieved without reducing the cell center's throughput. The cell edge's throughput supported in the worst-case direction is significantly enhanced by the cooperative linear transmit processing technique advocated. Explicitly, a cell-edge throughput of <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$\eta = 5\ \hbox{bit/s/Hz}$</tex></formula> may be maintained for an imperfect optical fiber model, regardless of the specific geographic distribution of the users.
